Answer:
1024
Step-by-step explanation:
1 division: 2
2 divisions: 2×2 = 4
3 divisions: 2×(2×2) = 8
The number of viruses is 2^n, where n is the number of divisions.
After 10 divisions, there are 2^10 = 1024 viruses.
Step-by-step explanation:
(3x-4y)×(3x-4y-(3x+4y))
(3x-4y)×(3x-4y-3x-4y)
(3x-4y)×(-8y)
-8y×(3x-4y
2a + 2b = c
Subtract 2a from both sides
2b = -2a + c
Divide both sides by 2
b = -a + (c/2)
